Effects on local EPSP amplitude of small dendritic branches in a model MSO neuron. A, Diagrams showing models with 3-μm-diameter, 150-μm-long dendrites and a 1-μm-diameter, 30-μm-long branch at a variable distance from the soma. The synapse location is either at the midpoint of the branch, 15 μm from the dendritic recording location on the trunk (left), or on the trunk itself 15 μm distal to the trunk dendritic recording site (right). B, Example traces for the recording locations shown in A with synaptic input on the branch or the trunk at 40 and 120 μm from the soma. C, EPSP amplitude at the trunk dendrite (thick lines) and soma (thin lines) as a function of distance from the soma for synapses located on either the dendritic trunk (purple) or branch (green).
